# CMake.js
|
||
|
|
|
||
|
|
[**CMake.js**](https://github.com/cmake-js/cmake-js) is a build tool that allow native addon developers to compile their
|
||
|
|
C or C++ code into executable form. It works like **[node-gyp](node-gyp.md)** but
|
||
|
|
instead of Google's [**gyp**](https://gyp.gsrc.io) tool it is based on the [**CMake**](https://cmake.org) build system.
|
||
|
|
|
||
|
|
## Quick Start
|
||
|
|
|
||
|
|
### Install CMake
|
||
|
|
|
||
|
|
CMake.js requires that CMake be installed. Installers for a variety of platforms can be found on the [CMake website](https://cmake.org).
|
||
|
|
|
||
|
|
### Install CMake.js
|
||
|
|
|
||
|
|
For developers, CMake.js is typically installed as a global package:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install -g cmake-js
|
||
|
|
cmake-js --help
|
||
|
|
```
|
||
|
|
|
||
|
|
> For *users* of your native addon, CMake.js should be configured as a dependency in your `package.json` as described in the [CMake.js documentation](https://github.com/cmake-js/cmake-js).
|
||
|
|
|
||
|
|
### CMakeLists.txt
|
||
|
|
|
||
|
|
Your project will require a `CMakeLists.txt` file. The [CMake.js README file](https://github.com/cmake-js/cmake-js#usage) shows what's necessary.
|
||
|
|
|
||
|
|
### NAPI_VERSION
|
||
|
|
|
||
|
|
When building N-API addons, it's crucial to specify the N-API version your code is designed to work with. With CMake.js, this information is specified in the `CMakeLists.txt` file:
|
||
|
|
|
||
|
|
```
|
||
|
|
add_definitions(-DNAPI_VERSION=3)
|
||
|
|
```
|
||
|
|
|
||
|
|
Since N-API is ABI-stable, your N-API addon will work, without recompilation, with the N-API version you specify in `NAPI_VERSION` and all subsequent N-API versions.
|
||
|
|
|
||
|
|
In the absence of a need for features available only in a specific N-API version, version 3 is a good choice as it is the version of N-API that was active when N-API left experimental status.
|
||
|
|
|
||
|
|
### NAPI_EXPERIMENTAL
|
||
|
|
|
||
|
|
The following line in the `CMakeLists.txt` file will enable N-API experimental features if your code requires them:
|
||
|
|
|
||
|
|
```
|
||
|
|
add_definitions(-DNAPI_EXPERIMENTAL)
|
||
|
|
```
|
||
|
|
|
||
|
|
### node-addon-api
|
||
|
|
|
||
|
|
If your N-API native add-on uses the optional [**node-addon-api**](https://github.com/nodejs/node-addon-api#node-addon-api-module) C++ wrapper, the `CMakeLists.txt` file requires additional configuration information as described on the [CMake.js README file](https://github.com/cmake-js/cmake-js#n-api-and-node-addon-api).
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
A working example of an N-API native addon built using CMake.js can be found on the [node-addon-examples repository](https://github.com/nodejs/node-addon-examples/tree/master/build_with_cmake#building-n-api-addons-using-cmakejs).
